Robert Wagner and Christopher Walken about the night of Natalie Wood's death

Clashing versions of what happened on the yacht shared by Wood, her actor-husband Robert Wagner and their friend, actor Christopher Walken, have contributed to the mystery of how the actress died on a Thanksgiving weekend 30 years ago, and who may have been responsible.

As investigators reopened the case after receiving new information, Dennis Davern, who was a captain of the yacht, appeared on national TV on Friday to restate his contention that a fight broke out between Wagner and Wood.

Davern said he originally lied to investigators about events on the yacht when he was interviewed after Natalie Wood's death. He accused Wagner of neglecting to do everything he could have done after her disappearance from the Splendour, and with intentionally keeping the investigation into her death low-profile.

Like Davern, Wagner contends a fight broke out.

In his bestselling 2008 memoir "Pieces of My Heart," he wrote that an argument over the acting profession led to Wood retreating to her cabin, while the dispute raged on between Wagner and Walken. Later Walken went to bed, according to Wagner, who, after staying up with Davern for a while, went looking for his wife and couldn't find her on board. He then noticed that the dinghy was gone.
